First Claim
1. A method of operating an automated warehouse system comprising:
- providing a multilevel storage structure including a plurality of storage locations arranged on sides of picking aisles disposed in rows on each level so that the picking aisles of a respective row are stacked one above the other, each level having more than one shelf level on which the plurality of storage locations are disposed;
providing at least one autonomous transport vehicle that travels along the stacked picking aisles for transferring items to and from the storage locations of the more than one shelf level;
disposing maintenance access zones within and coincident with the stacked picking aisles and defining the maintenance access zones at least in part by the sides with the storage locations of the more than one shelf level of the stacked picking aisles in at least one row, so that each maintenance access zone provides continuous access to multiple levels of the stacked picking aisles that are in communication with each other and the more than one shelf levels on the sides corresponding to each of the multiple levels of picking aisles; and
supporting the at least autonomous transport vehicle for travel through a respective picking aisle with at least one rail included within the picking aisles, where the at least one rail is common to the more than one shelf level of at least one level of the stacked picking aisles and the at least one rail is configured so as to provide access to the more than one shelf level of the at least one level of the stacked picking aisles.

Abstract
A maintenance access system for a storage and retrieval system having a storage and retrieval space and automated transport vehicles disposed in the space. The system includes at least one maintenance access control unit associated with a portion of the space, at least one barrier in the space and defining a boundary of the portion of the space and configured to substantially prevent the passage of the vehicles past the at least one barrier, and a controller connected to the control unit, the controller being configured to receive a signal from the at least one control unit for isolating the portion of the space associated with the at least one control unit, where the controller in response to the signal closes the at least one barrier isolating the portion of the space and effects the removal from or shutting down of vehicles within the portion of the space.
